A demonstration is provided of using the technique of computer simulation for analyzing scheduling problems in Naval Shipyards. A model is formulated for multiple ship, concurrent, sonar SQS-23 TRAM overhauls at the Long Beach Naval Shipyard. This model is an extension of PERT and considers the effect of probabilistic activity times and limited personnel resources. The TRANSIM simulator is utilized to assist in predicting the ship overhaul times and manpower utilization under different conditions. Two experiments are conducted which consider changes in relative overhaul commencement dates and modifications to the personnel resource levels. A complete description of the conceptual and computer models and the input coding are included in the report. Author
